Hot Sale Snl7 3p Series (MCB) Miniature Circuit Breaker 63A 10ka​

GENERAL

SNL7 series high breaking capacity mini circuit breaker is used in
AC50/60Hz, rated voltage of 230V

3, 4 poles 400V, rated current to 63A for overload and
short-circuit protection as well as for unfrequented switching
under normal case.It is used extensively for industry, commercial
and household.This product conform to IEC60898 standard.

1.Application:For protecting cables and equipments against
overload and short circuit.

2.General rules for choosing MCB.

a.Technical data of the network at the point
considered

The earthing systems,short-circuit current at the circuit breaker
installation point,which must always be less than the breaking
capacity of this device,network normal voltage.

b.There are 3 curvve characteristics for
magnetic operation:

B curve (3-5In) protection and control of the circuits against
length cables in TN and IT systems.

C curve (5-10In) protection and control of the circuits against
overloads and short-circuits; protection for resistive and
inductive loads with low inrush current.

D curve (10-14In) protection and control of the circuits against
overloads and short-circuits; protection for circuits which supply
loads with high inrush current at the circuit closing (LV/LV
transformers,breakdown lamps.)

Advantages:

High breaking capacity , all rated current can reach 6KA;

Many kinds of accessories can be chosen, in modularize and
flexibility combine that make the customer install conveniently;

The cover and function parts both are made of inflaming retarding,
bear high temperature and bear impact plastic;

The breaker is applicable to lighting distribution system in
industrial enterprise, commercially district, high-rise building
and dwelling house.

General rules for choosing MCB,For protecting cables and equipments
against overload and short circuit.

a. Technical date of network at the point considered:

The earthing systems,short-circuit current at the circuit breaker
installation point ,which must always be less than the breaking
capacity of this device,network normal voltage.

b. There are 3 curve characteristics for magnetic operation:

B curve (3-5 ln) protection and control of the circuits against
length cables in TN and IT systems.

C curve (5-10 ln) protection and control of the circuits against
overloads and short-circuits;protecton for resistive and inductive loads with low inrush
current.

D curve (10-20 ln) protection and control of the circuits against
overloads and short-circuits;protection for circuits which supply loads with high inrush current
at the circuit closing (LV/LV transformers,breakdown lamps)
